| # CIS-2 conformance vector: matvec_v1 |
| # op=matvec, spec ref: docs/CIS2_SPEC_v0.2.md §5.2 (Matvec), which in turn |
| # depends on §5.1 (strict left-to-right sequential dot product, `dot_seq`). |
| # |
| # Fields are `key=value`. `out_features`/`in_features` are plain decimal |
| # integers (small config constants, no float-parsing ambiguity). |
| # `w_bits` is `out_features * in_features` values, ROW-MAJOR (row `o`'s |
| # `in_features` entries first, then row `o+1`, ...), each a |
| # comma-separated `0x`-prefixed 32-bit hex IEEE-754 binary32 bit pattern |
| # (per tests/conformance/README.md's general convention). `x_bits` is |
| # `in_features` values, the shared input vector. |

| # Row 0 is §5.1's own worked example, verbatim: w[0,:] = [1e8, 1.0, -1e8] |
| # dotted against x = [1,1,1] MUST give exactly 0.0_f32 (the `1.0` term is |
| # lost to rounding against the 1e8 partial sum) -- a conforming |
| # implementation MUST reproduce this exact cancellation, not just "close". |
| # Row 1 and row 2 use small exactly-representable values (no order |
| # sensitivity) as a plain-arithmetic sanity check alongside the |
| # order-sensitive row 0. |
